i V Application filed April 3, B99. Serial No. 711.4175. (No model.) I I To all whom it nm yc'o'ncern: Y

Be it linowntha-t I; JULIUS PROEGER, of. Grecnsb-urg, in the county of \Vcstmoreland and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for .Making Hollow Glass Articles, of which the following'is a full, clear, and exact description, reference being had to the accompanying 2 is a top plan view of "the same, and Fig. 3 is.

drawings, forming part of this specification,

My invention relates to the formation of hollow glass articles by shaping and then blowing; and its object is to provide an improved apparatus for forming sucharticles whereby all danger of collapsing of the walls-of the blank after shaping or pressing prevented,

and'a simple-and eitective means for obtaining such articles is provided.

Heretofore informing articles by pressing and thenblowing the walls of the pressed hollow article would collapse andweld to each 1 other before blowing, so as to prevent the proper formation of the article. I have entirely overcome this di fiiculty by shaping only one end of the article in the'iirst step, leaving the body of the article solid, and then admit ing air to a small indentation in the finished end, sons to blow the :article into shape.

- fit upon the curved surface of the stationary 1 guide block or section 3, and to theirouter ends are secured the divided blank inolds 8.

The intermediate stemsof the holders are is bolted to the rotating hollow shaft 11, surmounted in'bcarings 9 upon a ring 10, which rounding the standard 2. I have shown six blank-molds as provided; but it is evident that any desired number may be used.

There are two working stations for this por tion of the machine, A being the shaping-star of cylinder 19 through port 29, controlled by tion and B the blank-blowing station. At the station A are provided vertical standards '12, v between which is carried a guide 13 i'o'r'a hollow cylinder 14, having at its upperend a head 15, adapted to fi't'neatly' within the re cess-he'ad'of the mold.- The head 15 is provided with a central pin 16, which enters the mouth of the glass article, which I have shown, as for a bottle, and around the .pin are a 'series of suction-ports 17, which lead from inside the cylinder to the head of the opening in the mold when the head is forced up against themold. The cylinder ii is carried upon arms or brackets 18, secured to a lower cylinder'lfl, the lower head of which is secured to thehollow piston-rod 2.0 of a piston 21 withina cylinder 22. The three cylinders 14, 19, and 522 are arranged in tandem, one above the other, and a piston 23 in cylinder 19 is provided with a downwardly-depending stem 24 within the hollow rod 20, the-lower end of the stem 21L resting upon the upperpacked end of a central post 25, which extends upwardly from the center of the lower headof cylinder 22; An upwardly-projectin'g rod or stem 26 on'the piston passes through a stuffing-box 27 and is securedto-piston 28 within the cylinder 14. The head 15 is forced into position against the end of the mold by admitting fluid into the lower Llld'Of' cylinder 22, and to produce the exhaustion of the air within the upper cylinder lithe fluid under pressure is admitted into the upper end 5 valve 30. The valve 30 is provided with a depending angular stem guided within a. hole in the lower head of the valve-casing and to which leads the fluid-supply pipe 81, consist ing of a flexible hose. The valve is also providedwith an upwardly exl ending angular stem, which is guided in a plungerhead 32,

having a stem 33. In the casing 35 for the plunger-head 32 isprovided an exhaust-port The stems of the valve are surrounded by spiral springs, so that there may bea slight movement of the plunger-head 32 without moving the valve. The frame is provided with a. leveling-finger 34: to contact with the molds at station A. i we The action of this part of the apparatus is as follows: Fluid under pressure beingsupthe mold the stem plied to the lower end of cylinder 22 and to the valve,will;forcc the valve down. The fluid entering the upper end of the cylinder 19 will force down the piston 23, which will draw down the piston in the upper cylinder 14, and thus suck down the glass within the moldcavity and finish the mouth of-the bottle within the detachable. head-clamp or mold-ring. The compressed fluid then being exhausted by turningvalve 62, as hereinafter described, thehrppcr cylinders will descend with the lower piston 21, and as the plunger-head 32 is' released it will be forced up, opening the exhaust from cylinder 151, so that as the parts are lowered the piston 28 will be brought into the upper end of the cylinder 1%. At the next station 13, I blow the blank, and between the stations A and 13 the cam-grooves upon the block 3 are arranged ,as shown,at the righthand po'rtion'of Fig.1., so that the holder willbe rotated to reverse the position of the mold and bring the finished mouth end'to the top. At this station is provided a lower stationary cylinder 37, containing plunger 38, having a form ing-head 30, which enters-the open lower end of the mold and forms the base of the blank blown against it; The blowing is effected by a hollow head 40, which is constructed and supported" the same as the.

head t1 for theblow-mold proper, 42. In each case this head is carried upon the projecting hollo'ii'gstem of a plunger 42', movable in a stationarycylinder 43, the stem containing a headed rod or pin is with a port leading along one side'and' thence through its lower portion. This stem extends down within the hollow head 41, and to it within the head is the mold-ring; This collar 45 normally pro- ;jccts slightly below the head 41, so that as the head is forced down into contact with the mold the ring will be lifted, and thus move up the headed end of the rod and allow the fluid under pressure to'pass down through the rod into the mold. The cylinder is singleacting, and the plunger is lifted by a spring 46 surrounding a stem 47, secured to the upper end of the plunger. The blank thus being blown into hollow form at station I3 is moved to the next station, at which the mold is opened by ,the handle 48, and the upper mold-ring is pulled outby its handles 49. This ring, with the blown blank depending there from, is then inserted in one of the finish blownnolds 42, six of which are mounted upon the rotary platform 50. This finishing-moldis then closed, and as it in its turnis' brought to the blowing-station C the bottle is blown into final shape. The platform 50 is secured to a toothed wheel 51, intermeshing with a wheel 52, which on the other side, engages.

toothed wheel 53', secured to the hollow shaft 11. The wheel 58 is rotated intermittently by a ratchet-wheel 5t secured to its hub and engaged by aspring-pressed pawl 55, carried 'on loose rings 56, connected by loose link 57 with a slide 58. The slide is operated by the hand-lever59, connected thereto by link 60, and is operated intermittently, so as to move each of the carriers one-sixth of a revolution at each stroke. The compressed fluid is led through a main G1 to a valve 62, from which leads a pipe 63 to the lower end of cylinder 22, the hose connection 31 leading from this pipe. A branch 64 also leads-from this pipe to the lower end of cylinder 37, and from the other side of the valve a pipe 65 leads upward] y through the vertical-standard 66 and thence over to the upper end of the cylinder for the blank-blowing station. A. flexible connection 67 leads from pipe'65 to the cylinder for the finish blowing-station-O. The valve 62 is operated by a foot-lever 68, and is so arranged that when the foot-lever is released fluid will be exhausted through all the pipes leading thereto The operation of my improved machine, is obvious from the above description. A blank is being finish-blown at the same time that another blank is being blown into hollow form at station B, and the month end of 'another is being shaped at station A, where a hole ismade in the month by the projecting pin lhe opera-tor .after dropping the hot glass into the open end of. the mold'at station A depresses the foot-lever, and thus sucks the glass down, so as to form the head.' At the same time the air will blow the other. two blanks at stations B and O. The operator then releasing the foot-lever moves the carriers by the hand-lever and at each such movement another operator opens the press- IIO mold beyond the station B, and removing the mold-ring and blank places them in one of .the finish-molds upon the platform 50. The .1

finishedarticle's are removed after passing. Y

station C, and the mold-rings again inserted in the press-molds,- whichare closed andagain brought into inverted position before reaching the station A.

The advantages of my invention result from the shaping of one end of the blank-and leaving the body of the blank solid before blowing, as this prevents any collapsing of'the walls of a pressed hollow blank when revers- 1.
